Comment(by unknown (google)):
I removed the theta_table and added a fuzz test. This uncovered a
problematic (A, E) pair which I moved into its own test. I looked through
the code for typos, but I couldn't find any; the buggy path would be the
long pade order 13. I also checked this particular (A, E) against R
expmFrechet as a black box, and they don't show this bug. So it's
probably a typo that I somehow can't see. I also tried not being clever
with LU decomposition but this didn't help.
